I will describe what it takes to simulate a brain model that has the size of the human brain - 1011 (one hundred billion) neurons and almost 1015 (one quadrillion) synapses. The simulation consists of a detailed model of thalamocortical system with 6-layered cortical structure and 3 thalamic nuclei. It has 18 neuronal cell types with anatomical arrangements corresponding to the striate cortex of cats. Simulation of 1 second of the model took 50 days on a cluster of 27 computers. I will describe what we learned from it and what we need to proceed further.
